PDE Q61

The assertion is correct because ocean currents are indeed a type of movement of surface water in the oceans. The reason is also correct, as ocean currents are primarily driven by planetary winds (like trade winds and westerlies), as well as differences in water temperature and density. These factors cause water to move in specific directions, forming patterns known as ocean currents.

• Option A: Both A and R are true and R is the correct explanation of A
  Correct. The reason accurately explains why ocean currents occur, directly supporting the assertion.

• Option B: Both A and R are true but R is not a correct explanation of A
  Incorrect. The reason clearly supports the assertion, so this does not apply.

• Option C: A is true but R is false
  Incorrect. The reason is factually accurate.

• Option D: A is false but R is true
  Incorrect. The assertion is also correct.
